Web Workersを用いてJavaScriptをマルチスレッド化する
長らくの間、JavaScriptはシングルスレッドな言語でした。重い処理を実行するたびにUI処理はブロックされ、マルチコアCPUは上手に使えない、それがJavaScriptの常識でした。ですが、Web Workersがあればそれが変わります。 Web Workersとは JavaScriptは、Workerという処理単位を持ちます。Workerはバックグラウンドで非同期に処理を行うための最も簡単な手法であり、JavaScriptに他の処理を妨げないタスクを実行する手段をもたらします。 しかしなぜWorkerという名前なのでしょうか。プログラマにとってなじみ深い「スレッド」ではいけなかったのでしょうか。 独立したメモリ空間 事実、Workerはスレッドのようなものと言えます。しかしながら、Workerにはプログラマが一般的に想像するスレッドとは少し違う点があります。スレッドというよりかは、ど
How JavaScript works: The building blocks of Web Workers + 5 cases when you should use them
This is post # 7 of the series dedicated to exploring JavaScript and its building components. In the process of identifying and describing the core elements, we also share some rules of thumb we use when building SessionStack, a JavaScript tool for developers to identify, visualize, and reproduce web app bugs through pixel-perfect session replay. If you missed the previous chapters, you can find t
Parallel.js: Parallel computing with Javascript
Parallel.js is a library for performing parallel computing in Javascript using web workers.Parallel Computing with Javascript Parallel.js is a tiny library for multi-core processing in Javascript. It was created to take full advantage of the ever-maturing web-workers API. Javascript is fast, no doubt, but lacks the parallel computing capabilites of its peer languages due to its single-threaded com
AngularJS and web workers
How can angularJS use web workers to run processes in the background? Is there any pattern I should follow on doing this? Currently, I am using a service that has the model in a separate web worker. This service implements methods like: ClientsFacade.calculateDebt(client1); //Just an example.. In the implementation, this method sends a message to the worker with the data. This allows me to abstrac

Web Workers
I recently wrote a program, Word Maestro, which requires extensive calculations in Javascript. The calculations, permutations and searching, are very CPU intensive and hangs the GUI when performed in the foreground. Web workers to the rescue! Web workers are supported by most moderns browsers with the exception of IE (Surprise!). IE10 release candidate supports them, but it is not very wide spread
